HUSKIN G-ROLL.

Specification of Letters Patent.

Serial No. 291,809.

To all "whom it moy concern:

Be it known that I, AUGUST RosnN'rIuL, residing in est Allis, in thecounty of Milwaukeeand State of lVisconsin, have invented new and usefulImprovements in Hnsking-Rolls, of which the following is a description,reference being had to the accompanying drawings, which are a part ofthis specification.

ltly invention has relation to improvements in corn-husking rolls.

One of the objects of the invention is to provide an improvedconstruction of rolls wherein a most effective and positive severing ofthe stalks from the ears is secured.

A further object resides in the provision of a construction whereby theends of the short ears of corn, or so-called nubbins, are prevented frombeing caught and held between the rolls a sufficient length of time toclog the said rolls and prevent etl'ective action thereof, theconstruction of the rolls being such that when the ends of the shortears or nulobins are carried between the rolls, the said ends are brokenand crushed to such an extentas to permit the husking pins to readilyeffect their function of husk ing or tearing off the husks from theears.

\Vith the above, and other incidental, objects in view, the inventionconsists of the devices and parts, or their equivalents, as hereinafterset forth.

In the accompanying drawing, Figure 1 is a. plan view of a series ofrolls embodying my invention; Fig. 2 is a cross section on the line 22of Fig. 1; Fig. 3 is a cross section on the line 3 3 of Fig. 1; and Fig.lis a cross section on the line -itit of Fig. 1.

My improved form of husking rolls is designed more especially for use inconnection with a corn-husking and shredding machine in which the cornis fed to the rolls in such manner that the forward ends of the rollsfirst grasp the stalks and break or sever said stalks from the ears, thesevered stalks being then carried between the rolls to shreddingmechanism (not shown),which mechanism breaks and shreds the stalks intoa number of pieces, the shredded portions being finally conducted out ofthe machine, and the ears of corn which are left on top of the rollssliding down said rolls and being acted upon by husking mechanism whichtears the husks from the cars, the said husks when so torn from the earspassing between the rolls and being acted upon by the shreddingmechanism, as in the case of the stalks, while the ears of corn strippedof their husks slide down the rolls and are discharged o'tl' of the rearends of said rolls.

Referring to the drawing, the numerals 5 and (3 indicate two of therolls of one pair, and 7 and 8 two of the rolls of another pair. Therolls are provided at opposite ends with journals 5) which are mountedin suitable bearings in the frame work of the machine. All the journalsat one cud have gear wheels 10 mounted thereon which mesh with eachother. One of the rolls may be positively driven in any desirablemanner, and in the drawing I show one of the journals at one end of oneof the rolls extended, and on this extended journal is mounted a gearwheel 11, which is driven by any suitable system of gearing. \Vhen thedriven roll is rotated, rotation will of course be imparted to the otherrolls by means of the intermeshing gears 10 in such manner that rolls 5and (3 will rotate toward each other, and rolls '7 and 8 toward eachother. Each one of the rolls is provided throughout its length with aspiral thread v12, the threads of the several rolls running in the samedirection.

The right hand ends of the rolls are the ends to which the corn-stalksand at tachcd ears are initially fed. Each one of the rolls from theright hand end thereof rearwardly for a desired distance is providedwith oppositely arranged surface recesses 13. IVithin these recesses 1are disposed metallic bars 14. It is desirable, in order to secure thebest results that the bars be so set and secured in the recesses thatthe advancing corner of the bar of one roll of a pair will strike thebar of the other roll of the pair at an intermediate point; of the saidbar of the other roll. ()no way of accomplishing this is to have the barin one recess tit against the shoulder at one end of said recess, andthe bar in the other recess lit against the end shoulder which isopposite to the shoulder against which the bar in the other recess tits.The same object can, of course be secured by setting the gears 10 indill'erent. relations to each other. The bars are detachably held inplace by means of bolts 15. These bolts provide for the removability ofthe bars when the acting corners of said bars become worn and it isdesired to present a new corner of a bar for action, or to substitute anew bar in place of the old one.

In order to give the butts or ends of the stalks an opportunity toinitially pass between the rolls, I form diametrically opposite faces ofthe forward or right hand ends of the rolls into flattened or lessrounded surfaces 16, which surfaces start from a desired pointrearwardly of the rolls and gradually taper forwardly, so that at theextreme forward ends of the rolls the spaces between these flattenedsurfaces is the greatest. From the fact that the two inner rolls rotatein a direction away from each other, the stalks are not carried betweenthese two rolls, but said stalks pass between each outside roll and theinner roll adjacent thereto.

By the provision of the recesses 13, the ends of the corn-stalks aremore effectually caught between the two pair of rolls (5-43 and 7 8) andcarried therebetween to a point below the rolls, where they may be actedupon by shredding mechanism. The angles formed at the corners of theserecesses are the active portions which engage the stalks and pull thesaid stalks between the rolls, and if no provision were made theseactive corners would, with continued use of the rolls, wear away, andthereby impair the efficiency of the rolls. It is for this reason that Iprovide the bars 14: which are secured in the recesses and arepreferably fitted against the active corners of the recesses. The wear,therefore, comes on the angles of these bars, and when these anglesbecome worn to such an extent as to impair their efiicieney, the bolts15 can be removed, and the bar either readjusted so as to present a newangle or corner, or a new bar may be substituted.

From the fact that the bars 14 are preferably set in their respectiverecesses, so that the advancing corner of one bar,

in the rotation of the rolls of a pair toward each other will strike thebar of the other roll at an intermediate point, a shearing action isproduced which serves to effectually grasp the stalks, as well as tobreak the same and crush and sever them from the ears.

It will be seen that in addition to the recesses 13, the outside rollshave other oppositely disposed recesses 17. These extra recesses are notabsolutely necessary, but by the provision thereof an additionalgripping effect on the stalks is secured. There is no particularnecessity for arranging the bars 14 in these extra grooves, inasmuch asthe wear on said grooves is not as great as in the case of the grooves18. Also, these extra grooves are not provided for the inner rolls,inasmuch as if provided they would have a tendency to draw thecorn-stalks around and upwardly between the two inner rolls.

After the ears of corn are severed from the stalks, the said ears slidedown the rolls, as previously pointed out, and are acted upon by thehusking mechanism. In the case of socalled nubbins or small ears ofcorn, the ends thereof are apt to become wedged in between the rolls andcause a clogging of the mechanism. It is, therefore, important toprovide means whereby if the ends of any of these short cars should becaught between the rolls, the said ends may be broken and crushed so asto give the husking pins an opportunity to completely tear off the husksfrom the ears. In some forms of rolls, a series of ribs have beenprovided around the rolls for the purpose of accomplishing the functionreferred to. This construction has not been attended with entirelysatisfactory results, inasmuch as the ribs form pockets therebetweeninto which the ends of the nubbins pass, and consequently the ribs areprevented from crushing and breaking the ends of the nubbins. In myimproved con struction, however, wherein the rolls are providedlongitudinally with spiral threads, the thread of one roll, in therotation of the rolls, may be said to be advancing in one direction,while the thread of the adjacent roll is advancing in the oppositedirection; or, in other words, the line of the thread of one roll isconstantly crossing the line of the thread of the other roll, with theresult that the ends of the nubbins are caught between the threads andbroken and crushed, and in this manner the husking mechanism ispermitted to readily tear the complete husks from off the ears, the saidhusks then passing between the rolls.

In order to accomplish the husking operation, I provide each of therolls with a series of husking pins 18.

IVhiIe 1 have herein shown and described two pair of husking rolls, yetI do not. wish to be understood as limiting myself thereto, inasmuch asonly one pair may be used, or more than two pair, without departing fromthe spirit and scope of my invention.
